Can you add a note to this docstring explaining how to add the feature to sub-classes?
If a package is not found, provide a better error message
that also explains how to install the package or gives the
user a link explaining what to do to install the package.
The supported methods are:
- Provide a link for windows
- Provide a command using a package manager for the OS
(For example: apt-get for Ubuntu/Debian, dnf and yum for
Fedora/CentOS/RHEL, brew and port for OSX)
